In the Data View window, missing string values will appear as blank cells.A string is a sequence of characters enclosed between the double quotes "…" Example: "abc123" "Hello World" "Hello, what is your name "
What is the function of string data type : A string is generally considered as a data type and is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. String may also denote more general arrays or other sequence (or list) data types and structures.
Is A string a data type
String (str or text)
It is a sequence of characters and the most commonly used data type to store text. Additionally, a string can also include digits and symbols, however, it is always treated as text.
How do you make a string value : Declaring strings
Just like we did with numbers, we are declaring a variable, initializing it with a string value, and then returning the value. The only difference here is that when writing a string, you need to surround the value with quotes.

Or, you might need to join (concatenate) several strings together, such as a last name and a first name.A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers. For example, the word "hamburger" and the phrase "I ate 3 hamburgers" are both strings.
How do you use string value : The java string valueOf() method converts different types of values into string.
